摘　　要：苏里格气田东区是苏里格气田外围一个具有很大天然气勘探潜力的区域。通过对苏里格气田东区二叠系盒8、山1段岩心、薄片资料、物性及压汞曲线特征等的分析,表明该区二叠系盒8、山1段储集岩以石英砂岩和岩屑石英砂岩为主,储集空间以次生溶孔和晶间微孔为主。属于低孔、低渗储层。并从沉积相、石英含量、成岩作用、微裂缝和砂体叠置分析了对储层的影响作用。储层物性主要受到沉积相和岩性的控制,成岩作用是影响储层优劣的决定性因素,微裂缝和砂体叠置在一定程度上改善了储层的孔隙度和渗透率。The eastern Sulige Gas Field is an area around the Sulige Gas Field which has large gas exploration potential. Based on the analysis of cores, slice data, property and capillary pressure curves of He-8 and Shan-1 formations of Permian reservoir in the eastern Suiige Gas Field, It is indicated that the reservoir rocks are dominated by quartz sandstone and - quartz sandstone ; the accumulation spaces are dominated by secondary dissolved pore and inter granular micro--pore of He- 8 and. Shah- 1 formation of Permian. It belongs to low- porosity and low- permeability reservoir. The reservoir is influenced by sedimentary facies, quartz content, diagenesis, micro--fractures and the pile of sandbody. Sedimentary facies and lithology control the reservoir property. The diagenesis is a critical factor that effect reservoir. Micro--fractures and the pile of sandbody improve the porosity and permeability of reservoir in a certain extent.
